A gas chromatograph/mass spectrometer (GC/MS), which has recently been acquired by the Chemistry Department of the University of West Florida is finding application in six undergraduate courses and in directed student research. Courses in basic organic chemistry, with a variety of majors, and advanced organic chemistry, with chemistry and allied health science majors are significantly enhanced by the availability of this system. Students are enabled to collect and evaluate firsthand data as, for example, (1) separating and identifying halocarbons by examining the molecular ions formed, (2) differentiating between isomers such as methyl p-hydroxybenzoate and p-methoxybenzoic acid by examining the fragmentation ions, (3) preparing and analyzing volatile organometallics, and (4) evaluating water supplies for organic contaminants.

一种气相色谱/质谱仪（GC/MS），最近已被 由西佛罗里达大学化学系获得 正在寻找六个本科课程的申请，并在指导 学生研究。基础有机化学课程，包括各种 专业，和先进的有机化学，与化学和联合健康 科学专业的学生通过这种可用性得到了显着提高， 系统学生能够收集和评估第一手数据， 例如，（1）通过检查卤代烃， 形成的分子离子，（2）区分异构体， 对羟基苯甲酸甲酯和对甲氧基苯甲酸， 裂解离子;（3）挥发性物质的制备和分析 有机金属，（4）评估有机供水 污染物。
